Hi all, I've installed KYB AGX on my 1992 TT, they are wonderful but the front strut nuts are flying, I setup them as before, 3 threads above the nut, but 10 miles after the struts moved upward and there are threads under the nut which is no more in contact with the chassis. I've read here that I must tight until end the nut but is it as simple as that ??? must-I re-tighten the nuts on the rear strut?? I put back all the rear trim already... I also replaced the insulators with a pseudo new version, which don't need the metallic "distance tube" like in this picture which seemed to maintain the strut in position. Is it right? does the new version of insulators still OK?
